Is cathode rays are material particles?
The cathode ray is a stream of electrons.
Who discovered negative charge?
J.J Thompson in 1897 demonstrated that cathode rays are composed of tiny, negatively charged subatomic particles called electrons.
Why do cathode rays produce sharp shadow of object placed in their path?
they are material particles!
Why did j.j reason the electrons must be a part of the atoms of all elements?
Cathode rays are negatively-charged particles.
What scientist designed an experiment that enabled the first successful detection of an individual subatomic particle?
J.J. Thomson (Sir Joseph John Thomson, 1856-1940), who demonstrated in 1897 that "cathode rays" consisted of negatively-charged particles, later named electrons.
What is Thompson's cathode ray?
homson conducted a series of experiments with cathode rays and cathode ray tubes leading him to the discovery of electrons and subatomic particles. Thomson used the cathode ray tube in three different experiments.
Is cathode rays are material particles?
The cathode ray is a stream of electrons.
Who discovered negative charge?
J.J Thompson in 1897 demonstrated that cathode rays are composed of tiny, negatively charged subatomic particles called electrons.
What is the charge of the particle in cathode rays?
Cathode rays are attracted to the positive charge on the anode! They are repelled by the negative charge on the cathode.
How did scientists discover subatomic particles?
somebody did something rite :POnly by experiments during long periods (exception are probable quarks and gluons proposed by a theory but not clearly identified by experiments).
What was the experimental evidence that Thomson had discovered the existence of a subatomic particle when working with cathode rays?
Thomson discovered the electron and proved that it existed without ever being able to see or isolate one. Electrons were the first subatomic particles to be discovered, the first particle of matter identified that was smaller than an atom. This discovery also finally provided some physical proof of, and description of, the basic unit that carried electricity. Thomson attached thin metal plates inside his cathode ray tube to a battery and showed that an electrical field could also deflect cathode rays.
What is the evidence that show cathode rays consists of charged particles?
in a cathode ray tube the cathode rays move towards the anode(positively charged) fixed plate.
Why are cathode rays deflected away from a negatively charged plate?
Alpha Rays are attracted to a negatively charged plate because they consist of positively charged particles.
How do charged plates affect the path of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
How do charged plates affect the plates of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
What is the charge of the cathode tube particles?
Cathode rays are high speed electrons. So they are negatively charged.
In the cathode ray tube where do the particles originate?
In a cathode ray tube (CRT), the particles, which are electrons, originate at the heated cathode, becoming the so-called cathode rays. The electrons stream off the cathode and rush over to the anode.
